Incorporating a flat sensor, the Elcometer 138 Bresle Salt Meter measures the conductivity of a sample, then automatically converts this to show the density of salts, negating the need for the user to do a manual calculation when working in accordance with ISO 8502-6 or ISO 8502-9.

Features:

• Highly precise measurements can be obtained from a single drop
• Out of range and low battery alarms
• Visual indication when ambient temperature is outside the operating range
